a, b Pretreatment facial and profile photographs of a 29-year-old female presenting with an orthodontically treated skeletal class III with facial asymmetry. c Lateral radiograph showing the dental camouflage of the class III malocclusion (ANB = − 3.5°) with severely retroclined mandibular incisors. d Posteroanterior radiograph displaying the skeletal asymmetry with an elongated left ramus causing deviation of the mandible to the right. e, f Intra-oral photographs reveal the outcome of the orthodontic camouflage. Note the deviation of the lower dental midline by 2 mm to the right. g–l Corresponding posttreatment facial, radiographic and occlusal records following the maxillary Le Fort I and USSO of the right mandibular ramus associated with genioplasty. Facial asymmetry was resolved (g, j), jaw relations rectified (ANB = 1.5°), and incisors in optimal inclinations over corresponding basal bones (i) and class I maintained (k, l). The midlines of the teeth, chin, and face were lined up
